WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 377,838, dated February14, 1888.

Application filed November 3, 1887. Serial No. 254,202. (No model.)

To all whom it may concern.-

Be it known that I, LEWIS MJPRATT, a citizen of the United States,residing at Belleville, in the county of Republic and State of Kansas,

5 have inventeda new and useful Improvement in Weather Strips, of whichthe following is a specification.

My invention relates to improvements in weather-strips; and it consistsin certain novel features, hereinafter described andclaimed.

In the accompanying drawings, which fully illustrate my invention,Figure 1 is a perspective view of a door providedfwith my improvedweather-strip and partially'opened. Fig. 2 is a I 5 longitudinal sectionof the lower portion of the door; and Fig. 3 is a detail perspectiveview of the bearing-plate. Fig. 4 is a detail view showing another formof bearing-plate.

Referring to the drawings by letter, A designates the door-frame, andBthe door, hinged thereto in the ordinary manner, as shown. The door isprovided in its lower edge with a recess, 0, which extends entirelyacross the width of the door, and in the side edges of the door I formthe grooves D, which communicate at their lower ends with the recess (3,and

in which the bearing-plates D are mounted. These bearing-plates D areprovided in their upper portions with the longitudinal slots E, throughwhich the retaining-screws F are inserted into the door and by means ofwhich the adjustment of the bearing-plates to and from'the lower edge ofthe door is made possible. The edges of the slots E are beveled, as mostclearly shown in Fig. 3, in order that the heads of the retaining-screwsmay be driven in flush with the outer surface of the plate, so that whenthe door is closed the said screws will not contact with and injure thedoor-jamb nor prevent the entire closing of the door. In the lower endsof the bearing-plates I form openings G, in which I journal the ends ofthe axis of a roller, H, which fits in the recess 0 in the lower edge ofthe door and projects slightly below the same, as shown. In Fig. 4 5 Ihave shown the bearing-plate as having its lower portion projectedoutward slightly. This construction brings the end of the roller nearerthe door, so as to prevent air passing between the jamb and the edge ofthe door.

In practice, when the door is closed, this roller rides over thethreshold and effectually. closes the space between the lower edge ofthe door and the thresho1d,-thereby preventing the entrance of cold air,as will be readily understood. The roller can be readily set to projectmore or less from the lower edge of the I door, according as the spacebetween the same and the threshold may be greater or less, by adjustingthe bearing-plates, as will be readily 6o understood.

It will be seen that I haveprovided a very\ simple and efficient device,which can be nianufactored at a small cost and can be readily appliedand operated by an unskilled person.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s- I The combination of the door having thehorizontal recess 0 in its lower edge, and the vertical grooves D in itsside edges, the plates D, fitted in the grooves D, and having thelongitudinal slots E, provided with beveled edges, theretaining-screwsinserted through said slots into thedoor, and the rollerH, jour- 7 naled in and between the lower'ends of the plates androtating in the recess 0, substan tially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in 80 presence of two witnesses.

LEWIS M. PRATT.
